Photospheric Imprints of Coronal Electric Currents, I. Magnetic Structure Near Polarity Inversion Lines
Brian T. Welsch, Peter W. Schuck, Mark G. Linton
Flares and coronal mass ejections (CMEs) are powered by magnetic energy stored in coronal electric currents. Here, we use photospheric vector magnetic field observations to study c…
Towards a Robust Estimate of the Solar Photospheric Poynting Flux and Helicity Flux
Jiayi Liu, Xudong Sun, Peter W. Schuck +1
The observed solar photospheric magnetic fields and Doppler velocities are frequently used to quantify the Poynting flux and helicity flux. Multiple methods have been developed for…
Simulating the photospheric to coronal plasma using magnetohydrodynamic characteristics III: validation including gravity, flux emergence, and an eruption
Lucas A. Tarr, N. Dylan Kee, James E. Leake +2
Solar eruptions arise from instabilities or loss of equilibria in the solar atmosphere, but routinely inferring the precise magnetic and plasma properties that lead to eruptions is…
Filament Mass Losses Forced by Magnetic Reconnection in the Solar Corona
Craig D. Johnston, Lars K. S. Daldorff, Peter W. Schuck +4
Recent observations of the solar atmosphere in cool extreme ultraviolet (EUV) lines have reported the prevalence of coronal rain falling from coronal cloud filaments that are assoc…
Simulating the photospheric to coronal plasma using magnetohydrodyanamic characteristics II: reflections on non-reflecting boundary conditions
N. Dylan Kee, Lucas A. Tarr, Peter W. Schuck +2
We present our implementation of non-reflecting boundary conditions in the magnetohydrodynamics (MHD) code LaRe3D. This implementation couples a characteristics-based boundary cond…
What Can DKIST/DL-NIRSP Tell Us About Quiet-Sun Magnetism?
Jiayi Liu, Xudong Sun, Peter W. Schuck +1
Quiet-Sun regions cover most of the Sun's surface; its magnetic fields contribute significantly to the solar chromospheric and coronal heating. However, characterizing the magnetic…
